Ratio pyrometers for high-temperature applications

Instrotech, the local representative for Optris, has intro duced the CSvision series of ratio pyrometers to the South African market. With a range from 300°C to 3 000°C, the pyrometers make it possible to measure the temperature of metals, melts or ceramics without contact, safely and reliably from different distances. Infrared pyrometers must meet high demands, espe cially in metallurgy where they are often used under harsh conditions, and they must always deliver reliable results. In high temperature environments, smoke, steam, or dust often impede a clear view of the measured object and affect the measurement signal. In these conditions, ratio pyrometers provide stable measured values, compared to single-channel pyrometers, even with dirty optics or objects that move within the measuring field, such as metal rods or wires. The new CSvision is equipped with the innovative Smart Ratio Mode (SRM) which enables it to master especially challenging applications with variable emissivity ratios. The built-in video sight and motorised focus, which can be operated via software or app, allow for the pyrometer to be focused on the selected object. The switchable two-stage brightness reduction filter ensures optimum viewing conditions, even with

very hot, bright objects. Together with the crosshair laser, which is also standard, this ensures simple sensor alignment under all conditions. The CSvision R1M offers an optical reso lution of up to 150:1 and a measuring range of 600°C to 3 000°C with a spectral range of 0.8 to 1.1 μm – in harsh industrial environments with temperatures up to 65°C without cooling. The R2M has an optical resolution of 75:1 and a spectral range of 1.45 to 1.75 μm. This al lows temperatures to be measured from as low as 300°C to 1 400°C in environments at up to 60°C without cooling. The CSvision series offers an easy-to-use solution that can be set up quickly. The infrared thermometers have an interface to the IRmobile Android app and CompactPlus Connect software, allowing for easy video alignment and real-time process monitoring. Two analogue outputs are available for process integration and digital interfaces, such as RS485 or Modbus RTU.
